Sub-10-nm aerosols experience internal pressures much higher than the atmosphere in which they float.[17]

Reactions experiencing concomitant constriction molar volume are accelerated in nanoparticles.[17]

The constrictive force of the interface can change aerosol viscosity and induce phase change.[17]

Hydroperoxides are more active as cloud condensation nuclei (CCN) than implied by prior water-hydroperoxide interaction coefficients. We used CCN measurements for a series of synthesized hydroperoxide compounds to provide updated parameters for CCN activity modeling via the widely-adopted UNIFAC model.[9]

The cloud condensation nuclei (CCN) activity of particles containing strong surfactants deviates strongly from predictions accounting only for surface tension. Predictions accounting for bulk-to-surface partitioning of surfactant molecules performed better, however there remain limitations in the ability of simple models to describe surfactant behavior in aerosols.[8,8a]

The ability of organic compounds to promote cloud droplet nucleation (CCN) increases with the addition of oxygenated functional groups in the order hydroxyl (OH) >> carboxyl (C(=O)OH) > hydroperoxide (COOH) > nitrate (ONO2) >> methylene (CH2). Nitrate and methylene groups decreased CCN efficiency.[5]

Aerosols take up water under humidified conditions. Atmospheric applications abound at very high RH, but the difficulty of performing humidified measurements increases exponentially above 90%. We report aerosol-water activity coefficients at relative humidities of up to 99%.[3]

The hygroscopicity of different compounds found in secondary organic aerosol can shift as a result of different environmental processes (different RH during gas-phase chemistry, left panels; different amount of irradiation, right panels). We used liquid chromatography coupled to a measurement of cloud condensation nuclei (CCN) efficiency to detect these shifts and learn something about the underlying mechanism.[1]
